Description

L'invention concerne le domaine du stockage et du transport de bouteilles de fluide sous pression et notamment de gaz sous pression de construction composite.The invention relates to the field of storage and transport of cylinders of pressurized fluid and in particular pressurized gas of composite construction.

Pour stocker et transporter des bouteilles de fluide sous pression et notamment de gaz sous pression, on utilise, de manière connue, des cadres dans lesquels les bouteilles sont montées horizontalement ou verticalement. Les bouteilles sont souvent disposées de manière jointive soit côte à côte soit en quinconce dans lesdits cadres et sont maintenues transversalement les unes aux autres généralement par des sangles, des barres ou des colliers métalliques.To store and transport bottles of fluid under pressure and in particular of gas under pressure, frames are used, in a known manner, in which the bottles are mounted horizontally or vertically. The bottles are often arranged in a contiguous manner either side by side or staggered in said frames and are held transversely to each other generally by straps, bars or metal collars.

Plus particulièrement, les bouteilles sont fixées à une première extrémité par liaison mécanique fixe à une partie du cadre au moyen d'une première pluralité d'organes de retenue par exemple vis/écrou et sont fixées à une seconde extrémité par liaison mécanique fixe au moyen d'une deuxième pluralité d'organes de retenue par exemple vis/écrou.More particularly, the bottles are fixed at a first end by a fixed mechanical connection to a part of the frame by means of a first plurality of retaining members, for example screws/nuts, and are fixed at a second end by a fixed mechanical connection by means a second plurality of retaining members, for example screw/nut.

Ce type de configuration de stockage connue présente notamment l'inconvénient de ne s'adapter ni à l'expansion éventuelle des bouteilles lors de leur remplissage, ni à la géométrie de la seconde extrémité des bouteilles et à ses dimensions qui varient selon les fabricants. En outre, certaines configurations proposant un stockage de bouteilles de manière jointive détériore la surface des bouteilles par abrasion, en particulier les fibres des bouteilles lorsque celles-ci sont de construction composite.This type of known storage configuration has the particular drawback of adapting neither to the possible expansion of the bottles during their filling, nor to the geometry of the second end of the bottles and to its dimensions, which vary according to the manufacturers. In addition, certain configurations proposing storage of bottles in a contiguous manner deteriorate the surface of the bottles by abrasion, in particular the fibers of the bottles when the latter are of composite construction.

L'invention a pour but de remédier à tout ou partie des inconvénients précités.The object of the invention is to remedy all or part of the aforementioned drawbacks.

L'invention a pour objet une cassette de stockage pour au moins une bouteille de fluide sous pression, ladite cassette de stockage étant destinée à être montée dans une structure primaire d'un cadre de stockage, et comprenant au moins un premier organe de retenue configuré pour coopérer fixement avec une première extrémité d'une bouteille, et au moins un deuxième organe de retenue configuré pour coopérer avec une seconde extrémité de la bouteille, le deuxième organe de retenue étant configuré pour maintenir la position de la seconde extrémité de la bouteille tout en présentant au moins un degré de liberté déterminé.The subject of the invention is a storage cassette for at least one bottle of pressurized fluid, said storage cassette being intended to be mounted in a primary structure of a storage frame, and comprising at least a first retaining member configured to cooperate fixedly with a first end of a bottle, and at least one second retainer configured to cooperate with a second end of the bottle, the second retainer being configured to maintain the position of the second end of the bottle while with at least one determined degree of freedom.

Le document WO2012071593 A décrit un dispositif conforme au préambule de la revendication 1.The document WO2012071593 A describes a device according to the preamble of claim 1.

La cassette de stockage selon l'invention telle que définie dans les revendications présente l'avantage de pouvoir absorber l'expansion du volume des bouteilles notamment lors de leur remplissage, tout en bloquant lesdites bouteilles en rotation de par la fixation ferme prévue au niveau de la première extrémité de chaque bouteille. Ainsi, la cassette selon l'invention forme un ensemble solidaire de bouteilles fixées fermement à une extrémité et de manière flottante à l'autre extrémité. Autrement dit, il n'existe aucune liaison mécanique ferme au niveau de la deuxième extrémité de chaque bouteille, ce qui permet un mouvement longitudinal des bouteilles dans leur zone de retenue.The storage cassette according to the invention as defined in the claims has the advantage of being able to absorb the expansion of the volume of the bottles in particular during their filling, while blocking the said bottles in rotation by the firm fixing provided at the level of the first end of each bottle. Thus, the cassette according to the invention forms an integral assembly of bottles fixed firmly at one end and so floating at the other end. In other words, there is no firm mechanical connection at the second end of each bottle, which allows longitudinal movement of the bottles in their retaining zone.

Dans la présente demande, on appelle « degré de liberté » dans une liaison, les mouvements relatifs indépendants d'un solide par rapport à l'autre autorisés par cette liaison.In the present application, the term “degree of freedom” in a connection refers to the independent relative movements of one solid with respect to the other authorized by this connection.

Selon une caractéristique de l'invention, la cassette de stockage est configurée pour recevoir au moins une bouteille disposée verticalement ou horizontalement par rapport au sol.According to one characteristic of the invention, the storage cassette is configured to receive at least one bottle placed vertically or horizontally with respect to the ground.

Selon une caractéristique de l'invention, la cassette de stockage comprend au moins une première tôle s'étendant dans une première direction, la première tôle comprenant au moins un orifice de passage conformé pour recevoir au moins une partie de la première extrémité de la bouteille en position montée.According to one characteristic of the invention, the storage cassette comprises at least a first sheet extending in a first direction, the first sheet comprising at least one passage orifice shaped to receive at least part of the first end of the bottle in mounted position.

Avantageusement, la première direction est sensiblement perpendiculaire à la direction de montage de la au moins une bouteille lorsque la bouteille est montée dans la cassette.Advantageously, the first direction is substantially perpendicular to the mounting direction of the at least one bottle when the bottle is mounted in the cassette.

Selon une caractéristique de l'invention, la cassette de stockage comprend plusieurs orifices de passages équipant la première tôle et configurés pour recevoir chacun la première extrémité de chaque bouteille montée ou destinée à être montée dans la cassette de stockage, les orifices de passage étant agencés sur la première tôle à distance les uns des autres de manière régulière ou irrégulière. Ceci permet d'éviter les contacts entre les bouteilles et l'usure de ces dernières par frottement.According to one characteristic of the invention, the storage cassette comprises several passage orifices fitted to the first sheet and each configured to receive the first end of each bottle mounted or intended to be mounted in the storage cassette, the passage orifices being arranged on the first sheet at a distance from each other in a regular or irregular manner. This makes it possible to avoid contact between the bottles and wear of the latter by friction.

Selon une caractéristique de l'invention, la première tôle est équipée du premier organe de retenue de la cassette de stockage, ledit premier organe de retenue étant configuré pour coopérer avec une collerette équipant la première extrémité de la bouteille.According to one characteristic of the invention, the first sheet is equipped with the first retaining member of the storage cassette, said first retaining member being configured to cooperate with a flange fitted to the first end of the bottle.

Préférentiellement, le au moins un organe de retenue présente un filetage interne conformé pour coopérer avec un filetage externe ménagé sur la collerette de la première extrémité de la bouteille, ce qui permet le blocage axial de la bouteille à l'intérieur de la cassette de stockage.Preferably, the at least one retaining member has an internal thread shaped to cooperate with an external thread provided on the collar of the first end of the bottle, which allows the axial locking of the bottle inside the storage cassette. .

Selon une caractéristique de l'invention, la cassette de stockage comprend au moins une deuxième tôle s'étendant dans la première direction et positionnée en regard de la première tôle à une distance déterminée.According to one characteristic of the invention, the storage cassette comprises at least a second sheet extending in the first direction and positioned facing the first sheet at a determined distance.

Selon une caractéristique de l'invention, la distance déterminée entre la première tôle et la deuxième tôle est fonction des dimensions des bouteilles à monter dans la cassette de stockage et en particulier en fonction de la longueur des bouteilles à monter dans la cassette de stockage. Préférentiellement, la distance est comprise entre 1000 mm et 2000 mm.According to one characteristic of the invention, the distance determined between the first sheet and the second sheet is a function of the dimensions of the bottles to be mounted in the storage cassette and in particular according to the length of the bottles to be mount in the storage cassette. Preferably, the distance is between 1000 mm and 2000 mm.

Selon une caractéristique de l'invention, la cassette de stockage comprend un deuxième organe de retenue correspondant à un orifice de passage ménagé sur la deuxième tôle et conformé pour recevoir au moins partiellement la seconde extrémité de la bouteille.According to one characteristic of the invention, the storage cassette comprises a second retaining member corresponding to a passage orifice provided on the second sheet and shaped to at least partially receive the second end of the bottle.

Selon une caractéristique de l'invention, la cassette de stockage comprend plusieurs organes de retenue correspondant à des orifices de passage ménagés sur la deuxième tôle et configurés pour recevoir chacun la seconde extrémité de chaque bouteille montées dans la cassette de stockage, lesdits organes de retenue étant agencés à distance les uns des autres de manière régulière ou irrégulière, ce qui permet d'éviter les contacts entre les bouteilles et l'usure de ces dernières par frottement.According to one characteristic of the invention, the storage cassette comprises several retaining members corresponding to passage orifices provided on the second sheet and configured to each receive the second end of each bottle mounted in the storage cassette, said retaining members being arranged at a distance from each other in a regular or irregular manner, which makes it possible to avoid contact between the bottles and wear of the latter by friction.

Selon une caractéristique de l'invention, chaque orifice de passage de la pluralité de la deuxième tôle sont conformés pour coopérer par complémentarité de forme avec la seconde extrémité de chaque bouteille, ce qui permet l'indexation et le blocage en rotation de chaque bouteille tout en conservant les propriétés d'adaptation de la cassette de stockage.According to one characteristic of the invention, each passage orifice of the plurality of the second sheet is shaped to cooperate by form complementarity with the second end of each bottle, which allows the indexing and the blocking in rotation of each bottle while retaining the adaptation properties of the storage cassette.

Préférentiellement, chaque orifice de passage présente une forme d'étoile multi-branches.Preferably, each passage orifice has the shape of a multi-pointed star.

Selon une caractéristique de l'invention, la cassette comprend un dispositif de blocage configuré pour relier la première tôle à la deuxième tôle tout en présentant au moins un degré de liberté. De préférence, ce degré de liberté autorise un débattement (jeu ou positionnement adaptable limité) selon une direction parallèle à l'axe longitudinal des bouteilles. Ce degré de liberté (jeu) peut être limité par exemple par un système de butée(s).According to one characteristic of the invention, the cassette comprises a locking device configured to connect the first sheet to the second sheet while having at least one degree of freedom. Preferably, this degree of freedom allows movement (play or limited adaptable positioning) in a direction parallel to the longitudinal axis of the bottles. This degree of freedom (play) can be limited for example by a system of stop(s).

Avantageusement, le dispositif de blocage présente une élasticité longitudinale d'environ 5% à 30% et préférentiellement de 10% ; pour une longueur initiale d'environ 1000 mm à 2000 mm et préférentiellement, d'environ 1500 mm ; ce qui représente une élongation comprise entre environ 5 à 60 cm et préférentiellement, 10 à 20 cm.Advantageously, the locking device has a longitudinal elasticity of about 5% to 30% and preferably 10%; for an initial length of around 1000 mm to 2000 mm and preferably around 1500 mm; which represents an elongation of between about 5 to 60 cm and preferably 10 to 20 cm.

Le dispositif de blocage permet d'absorber l'allongement possible des bouteilles et donc l'éloignement potentiel des première et deuxième tôles l'une par rapport à l'autre.The blocking device makes it possible to absorb the possible elongation of the bottles and therefore the potential distance of the first and second sheets from each other.

Selon une caractéristique de l'invention, le dispositif de blocage comprend au moins un ensemble vis/écrou s'étendant dans une direction sensiblement perpendiculaire à la direction dans laquelle s'étendent la première tôle et la deuxième tôle.According to one characteristic of the invention, the locking device comprises at least one screw/nut assembly extending in a direction substantially perpendicular to the direction in which the first sheet and the second sheet extend.

Avantageusement, l'ensemble vis/écrou traverse la première tôle et la deuxième tôle.Advantageously, the screw/nut assembly passes through the first sheet and the second sheet.

Selon une autre caractéristique de l'invention, le dispositif de blocage comprend au moins deux ensembles vis/écrou, espacés l'un de l'autre.According to another characteristic of the invention, the locking device comprises at least two screw/nut assemblies, spaced from each other.

L'invention concerne également un cadre de stockage pour bouteilles, le cadre de stockage comprenant une structure primaire et au moins une cassette de stockage selon l'invention, ladite au moins une cassette étant montée dans la structure primaire.The invention also relates to a storage frame for bottles, the storage frame comprising a primary structure and at least one storage cassette according to the invention, said at least one cassette being mounted in the primary structure.

En particulier, la cassette est montée de façon amovible dans la structure primaire.In particular, the cassette is removably mounted in the primary structure.

Selon une caractéristique de l'invention, la structure primaire est définie par un ensemble mécano-soudée de barres et montants métalliques.According to one characteristic of the invention, the primary structure is defined by a mechanically welded assembly of metal bars and uprights.

Selon une caractéristique de l'invention, le montage des bouteilles dans la cassette est effectué indépendamment du cadre.According to one characteristic of the invention, the mounting of the bottles in the cassette is carried out independently of the frame.

Selon une caractéristique de l'invention, la structure primaire du cadre comprend au moins un élément de calage destiné à recevoir la deuxième extrémité d'au moins une bouteille.According to one characteristic of the invention, the primary structure of the frame comprises at least one wedging element intended to receive the second end of at least one bottle.

Selon une caractéristique de l'invention, en position montée, la deuxième extrémité de chaque bouteille repose sur un élément de calage de la structure primaire. Ainsi, une partie du poids des bouteilles est aussi soutenue par la structure primaire lorsque la cassette est montée dans la structure du cadre et lorsqu'au moins une bouteille est montée dans ladite cassette.According to one characteristic of the invention, in the mounted position, the second end of each bottle rests on a wedging element of the primary structure. Thus, part of the weight of the bottles is also supported by the primary structure when the cassette is mounted in the structure of the frame and when at least one bottle is mounted in said cassette.

Selon une caractéristique de l'invention, la cassette est fixée à la structure primaire au moyen d'au moins une liaison mécanique fixe au niveau de la deuxième tôle et au moyen d'au moins une liaison mécanique mobile au niveau de la première tôle. Ainsi, lorsque les bouteilles s'allongent, la première tôle est laissée libre de mouvement axial du fait du jeu permis par la au moins une liaison mécanique mobile jusqu'à une butée positionnée, par exemple définie par les collerettes montées sur les bouteilles.According to one characteristic of the invention, the cassette is fixed to the primary structure by means of at least one fixed mechanical connection at the level of the second sheet and by means of at least one mobile mechanical connection at the level of the first sheet. Thus, when the bottles lengthen, the first sheet is left free of axial movement due to the play allowed by the at least one movable mechanical connection as far as a positioned abutment, for example defined by the flanges mounted on the bottles.

On entendra par liaison mécanique mobile, dans la présente demande, une liaison mécanique de type boulon-écrou avec entretoise ou goupille ou système à ressort.By movable mechanical connection, in the present application, we mean a mechanical connection of the bolt-nut type with spacer or pin or spring system.

Selon une caractéristique de l'invention, la au moins une liaison mécanique est configurée pour guider et fixer la cassette sur la structure primaire au niveau de la partie supérieure de ladite cassette.According to one characteristic of the invention, the at least one mechanical connection is configured to guide and fix the cassette to the primary structure at the level of the upper part of said cassette.

Selon une caractéristique de l'invention, la cassette de stockage comprend un dispositif de verrouillage comprenant au moins un organe de verrouillage configuré pour traverser la structure de la cassette et plus préférentiellement la seconde extrémité de la bouteille lorsque cette dernière est creuse.According to one characteristic of the invention, the storage cassette comprises a locking device comprising at least one locking member configured to pass through the structure of the cassette and more preferably the second end of the bottle when the latter is hollow.

Selon une caractéristique de l'invention, la cassette de stockage comprend une pluralité de bouteilles.According to one characteristic of the invention, the storage cassette comprises a plurality of bottles.

Ainsi, il y a autant d'organes de retenue équipant la première tôle que de bouteilles prévues ou montées dans la cassette de stockage et/ou il y a autant d'orifices de passage ménagés sur la première tôle que de bouteilles prévues ou montées dans la cassette de stockage et/ou il y a autant d'organes de retenue équipant la deuxième tôle que de bouteilles prévues ou montées dans la cassette de stockage.Thus, there are as many retaining members fitted to the first sheet as there are bottles provided or mounted in the storage cassette and/or there are as many passage orifices provided on the first sheet as there are bottles provided or mounted in the storage cassette and/or there are as many retaining members fitted to the second sheet as there are bottles provided or mounted in the storage cassette.

Selon une caractéristique de l'invention, chaque bouteille comprend un corps, une première extrémité et une deuxième extrémité opposée à la première extrémité. Avantageusement, la première extrémité est destinée à être équipée d'un robinet ou d'une valve.According to one characteristic of the invention, each bottle comprises a body, a first end and a second end opposite the first end. Advantageously, the first end is intended to be equipped with a tap or a valve.

Selon une caractéristique de l'invention, la deuxième extrémité de chaque bouteille est conformée pour indexer et bloquer la bouteille en position, lorsque ladite bouteille est en position montée dans la cassette de stockage.According to one characteristic of the invention, the second end of each bottle is shaped to index and block the bottle in position, when said bottle is in the mounted position in the storage cassette.

Préférentiellement, la deuxième extrémité de chaque bouteille présente une section transversale polygonale non-circulaire, non hémisphérique.Preferably, the second end of each bottle has a non-circular, non-hemispherical polygonal cross-section.

Encore plus préférentiellement, la deuxième extrémité présente une section transversale en forme d'étoile à plusieurs branches conformées pour indexer la bouteille et bloquer la bouteille en rotation.Even more preferentially, the second end has a star-shaped cross-section with several shaped branches to index the bottle and lock the bottle in rotation.

Selon une caractéristique de l'invention, la longueur de la deuxième extrémité de la bouteille est supérieure à l'expansion longitudinale de ladite bouteille, ce qui permet d'éviter que la bouteille ne sorte de l'orifice de passage de la deuxième tôle.According to one characteristic of the invention, the length of the second end of the bottle is greater than the longitudinal expansion of said bottle, which makes it possible to prevent the bottle from coming out of the passage orifice of the second sheet.

Selon une autre caractéristique de l'invention, la structure primaire comprend au moins un élément intermédiaire ou entretoise configuré pour assurer l'interface entre chaque bouteille et la structure primaire. L'élément intermédiaire garantit l'absence de contact entre la bouteille et le cadre, par exemple contact métal-métal, qui donnerait lieu à une usure prématurée de la seconde extrémité de la bouteille et notamment un endommagement du revêtement par exemple anticorrosion réalisé sur cette zone de la bouteille.According to another characteristic of the invention, the primary structure comprises at least one intermediate element or spacer configured to provide the interface between each bottle and the primary structure. The intermediate element guarantees the absence of contact between the bottle and the frame, for example metal-metal contact, which would give rise to premature wear of the second end of the bottle and in particular damage to the coating, for example anti-corrosion, produced on this bottle area.

De préférence, le au moins un élément intermédiaire est une bague ou un joint en caoutchouc ou en élastomère. Avantageusement, le au moins un élément intermédiaire présente une dureté comprise entre 70 Shore A et 60 Shore D, de préférence entre 80 et 90 Shore A.Preferably, the at least one intermediate element is a rubber or elastomer ring or seal. Advantageously, the at least one intermediate element has a hardness of between 70 Shore A and 60 Shore D, preferably between 80 and 90 Shore A.

Selon une caractéristique de l'invention, le au moins un élément intermédiaire est amovible par rapport à la structure primaire.According to one characteristic of the invention, the at least one intermediate element is removable with respect to the primary structure.

Selon une caractéristique de l'invention, chaque au moins un élément intermédiaire est conformé pour recevoir et épouser la forme de la seconde extrémité de chaque bouteille sur une face intérieure.According to one characteristic of the invention, each at least one intermediate element is shaped to receive and match the shape of the second end of each bottle on an inner face.

Selon une caractéristique de l'invention, chaque au moins un élément intermédiaire est conformé pour recevoir et épouser la forme d'un logement ménagé sur la structure primaire sur une face extérieure.According to one characteristic of the invention, each at least one intermediate element is shaped to receive and match the shape of a housing provided on the primary structure on an outer face.

Le cadre de stockage 100 selon l'invention comprend une structure primaire 101 dans laquelle est disposée au moins une cassette de stockage 102 selon l'invention, comme illustré aux figures 1 à 3. La cassette de stockage 102 selon l'invention 103, est destinée à contenir une pluralité de bouteilles 103 de fluide sous pression et notamment de gaz sous pression comme illustré figure 3.The storage frame 100 according to the invention comprises a primary structure 101 in which is arranged at least one storage cassette 102 according to the invention, as illustrated in figures 1 to 3 . The storage cassette 102 according to the invention 103, is intended to contain a plurality of bottles 103 of fluid under pressure and in particular of gas under pressure as illustrated picture 3 .

Comme visible aux figures, la cassette de stockage 102 avec ses bouteilles 102 forme ainsi une entité physique distincte (séparable) du cadre 100 de stockage.As can be seen in the figures, the storage cassette 102 with its bottles 102 thus forms a separate physical entity (separable) from the storage frame 100.

Les bouteilles 103 sont disposées dans la cassette de stockage 102 verticalement ou horizontalement par rapport au sol. En outre, comme illustré en figure 1, l'agencement des bouteilles 103 dans la cassette de stockage 102 peut être selon une première configuration illustrée en figure 1 ou selon une deuxième configuration illustrée en figure 2. En figure 1, les bouteilles 103 sont alignées dans deux directions et agencées sans contact les unes avec les autres. En figure 2, les bouteilles 103 sont alignées dans une direction et agencées en quinconce dans une deuxième direction.The bottles 103 are placed in the storage cassette 102 vertically or horizontally with respect to the ground. Furthermore, as illustrated in figure 1 , the arrangement of the bottles 103 in the storage cassette 102 can be according to a first configuration illustrated in figure 1 or according to a second configuration illustrated in figure 2 . In figure 1 , the bottles 103 are aligned in two directions and arranged without contact with each other. In figure 2 , the bottles 103 are aligned in one direction and staggered in a second direction.

Le montage des bouteilles 103 dans la cassette de stockage 102 est effectué indépendamment du cadre de stockage 100 comme décrit ci-après en référence aux figures 9 à 14 selon un premier mode de réalisation ou selon un deuxième mode e réalisation comme représenté aux figures 19 à 23.The mounting of the bottles 103 in the storage cassette 102 is carried out independently of the storage frame 100 as described below with reference to the figures 9 to 14 according to a first embodiment or according to a second embodiment as shown in figures 19 to 23 .

La cassette de stockage 102 comprend au moins une première tôle 1 s'étendant dans une première direction sensiblement perpendiculaire à la direction de montage des bouteilles 103, comme illustré aux figures 3,4 et 5.The storage cassette 102 comprises at least a first sheet 1 extending in a first direction substantially perpendicular to the mounting direction of the bottles 103, as illustrated in Figs 3.4 and 5 .

Comme visible en figure 5, la première tôle 1 comprend une pluralité orifices de passage 3 conformés chacun pour recevoir la première extrémité 103a de chaque bouteille 103. Plus particulièrement, la première extrémité 103a de chaque bouteille 103 est équipée d'une collerette 103c passant à travers l'orifice de passage 3 et comprenant un épaulement venant en butée contre la première tôle 1. En outre, les orifices de passage 3 de ménagés sur la première tôle 1 sont agencés à distance les uns des autres de manière régulière.As seen in figure 5 , the first sheet 1 comprises a plurality of passage orifices 3 each shaped to receive the first end 103a of each bottle 103. More particularly, the first end 103a of each bottle 103 is equipped with a collar 103c passing through the orifice of passage 3 and comprising a shoulder abutting against the first sheet 1. In addition, the passage orifices 3 formed on the first sheet 1 are arranged at a distance from each other in a regular manner.

Dans l'exemple illustré notamment en figure 5, la première tôle 1 est équipée de la première pluralité d'organes de retenue 4 configurés pour coopérer chacun avec la collerette 103c équipant la première extrémité 103a de chaque bouteille 103. Préférentiellement, chaque organe de retenue 4 présente un filetage interne conformé pour coopérer avec un filetage externe ménagé sur la collerette 103c de chaque bouteille 103.In the example illustrated in particular in figure 5 , the first sheet 1 is equipped with the first plurality of retaining members 4 each configured to cooperate with the collar 103c fitted to the first end 103a of each bottle 103. Preferably, each retaining member 4 has an internal thread shaped to cooperate with an external thread provided on the flange 103c of each bottle 103.

Comme illustré aux figures 3, 7 et 8 notamment, la cassette de stockage 102 comprend au moins une deuxième tôle 2 s'étendant dans la première direction et positionnée en regard de la première tôle 1 à une distance déterminée.As shown in figure 3 , 7 and 8 in particular, the storage cassette 102 comprises at least a second sheet 2 extending in the first direction and positioned facing the first sheet 1 at a determined distance.

Dans l'exemple illustré en figure 8, la deuxième tôle 2 présente une pluralité d'orifices de passage 6 faisant office d'organes de retenue 6 de la seconde extrémité 103b de chaque bouteille 103. Les orifices de passage 6 ménagés sur la deuxième tôle 2 sont agencés à distance les uns des autres de manière régulière.In the example shown in figure 8 , the second sheet 2 has a plurality of passage orifices 6 acting as retaining members 6 of the second end 103b of each bottle 103. The passage orifices 6 provided on the second sheet 2 are arranged at a distance from each other. others on a regular basis.

Chaque orifice de passage 6 de la deuxième tôle 2 sont conformés pour coopérer par complémentarité de forme avec la seconde extrémité 103b de chaque bouteille 103. Dans l'exemple illustré aux figures 7 et 8, la seconde extrémité 103b de chaque bouteille 103 est de forme polygonale, de section transversale en forme d'étoile. Les orifices de passages 6 de la deuxième tôle 2 formant des organes de retenue 6 sont configurés pour maintenir la deuxième extrémité 103b de chaque bouteille 103 tout en présentant au moins un degré de liberté déterminé.Each passage orifice 6 of the second sheet 2 is shaped to cooperate by form complementarity with the second end 103b of each bottle 103. In the example illustrated in figures 7 and 8 , the second end 103b of each bottle 103 is polygonal in shape, with a star-shaped cross-section. The passage orifices 6 of the second sheet 2 forming retaining members 6 are configured to hold the second end 103b of each bottle 103 while having at least one determined degree of freedom.

Comme illustré, ce degré de liberté est notamment longitudinal c'est-à-dire que la deuxième extrémité 103b de la bouteille 103 peut avoir un jeu limité dans la deuxième tôle 2 selon la direction longitudinale de la bouteille.As illustrated, this degree of freedom is in particular longitudinal, that is to say that the second end 103b of the bottle 103 can have a limited play in the second sheet 2 in the longitudinal direction of the bottle.

Comme illustré aux figures 5 à 7, la cassette de stockage 102 comprend un dispositif de blocage 7 configuré pour relier la première tôle 1 à la deuxième tôle 2 tout en présentant au moins un degré de liberté. Le dispositif de blocage 7 comprend plusieurs ensembles vis/écrou s'étendant dans une direction sensiblement perpendiculaire à la direction dans laquelle s'étendent la première tôle 1 et la deuxième tôle 2. Chaque ensemble vis/écrou traverse la première tôle 1 et la deuxième tôle 2.As shown in figures 5 to 7 , the storage cassette 102 comprises a locking device 7 configured to connect the first sheet 1 to the second sheet 2 while having at least one degree of freedom. The locking device 7 comprises several screw/nut assemblies extending in a direction substantially perpendicular to the direction in which the first sheet 1 and the second sheet 2 extend. Each screw/nut assembly passes through the first sheet 1 and the second plate 2.

D'autres dispositifs de blocage équivalents sont envisageables (goujons, ...).Other equivalent locking devices are possible (studs, etc.).

Selon l'invention et comme visible en figure 8, la structure primaire 101 du cadre de stockage 100 comprend plusieurs éléments de calage 101a. En position montée, comme illustrée en figure 8, la deuxième extrémité 103b de chaque bouteille 103 repose sur un élément de calage 101a de la structure primaire 101.According to the invention and as visible in figure 8 , the primary structure 101 of the storage frame 100 comprises several wedging elements 101a. In mounted position, as shown in figure 8 , the second end 103b of each bottle 103 rests on a wedging element 101a of the primary structure 101.

Comme illustré en figure 7, la cassette de stockage 102 est fixée à la structure primaire 101 au moyen de liaisons mécaniques fixes 9 au niveau de la deuxième tôle 2 et au moyen de liaisons mécaniques mobiles 8 au niveau de la première tôle 1 comme visible aux figures 3 à 7.As illustrated in figure 7 , the storage cassette 102 is fixed to the primary structure 101 by means of fixed mechanical connections 9 at the level of the second sheet 2 and by means of movable mechanical connections 8 at the level of the first sheet 1 as visible in figures 3 to 7 .

Le montage d'une cassette de stockage 102 selon l'invention dans un cadre de stockage 100 selon un premier mode de réalisation va maintenant être décrit en référence aux figures 9 à 14.The mounting of a storage cassette 102 according to the invention in a storage frame 100 according to a first embodiment will now be described with reference to the figures 9 to 14 .

Les bouteilles 103 sont tout d'abord montées entre une première 1 et une deuxième tôle 2. Plus particulièrement la première extrémité 103a de chaque bouteille 103 passe à travers un orifice de passage 3 ménagé sur la première tôle 1 et la seconde extrémité 103b de chaque bouteille 103 passe à travers un orifice de passage 6 ménagé sur la deuxième tôle 2 comme visible en figure 9.The bottles 103 are first of all mounted between a first 1 and a second sheet 2. More particularly the first end 103a of each bottle 103 passes through a passage orifice 3 provided on the first sheet 1 and the second end 103b of each bottle 103 passes through a passage orifice 6 provided on the second sheet 2 as seen in figure 9 .

Comme illustré en figure 10, on fixe la première extrémité 103a de chaque bouteille 103 sur la première tôle 1 au moyen d'organes de retenue 4. Plus particulièrement, chaque première extrémité 103a de chaque bouteille 103 est équipée d'une collerette 103c filetée sur laquelle un organe de retenue 4, par exemple un écrou ou une bague de retenue, est vissé. En outre, la seconde extrémité 103b de chaque bouteille 103 est retenue par sa coopération par complémentarité de forme avec l'orifice de passage 6 ménagé sur la deuxième tôle 2. Chaque orifice de passage 6 de la deuxième tôle 2 forme donc un organe de retenue. Un système de type palan et un gabarit peuvent avantageusement être utilisés pour faciliter le montage des bouteilles 103 à l'intérieur de la cassette de stockage 102.As illustrated in figure 10 , the first end 103a of each bottle 103 is fixed on the first sheet 1 by means of retaining members 4. More particularly, each first end 103a of each bottle 103 is equipped with a threaded collar 103c on which a retaining member 4, for example a nut or a retaining ring, is screwed on. In addition, the second end 103b of each bottle 103 is retained by its cooperation by form complementarity with the passage orifice 6 provided on the second sheet 2. Each passage orifice 6 of the second sheet 2 therefore forms a retaining member . A system of the hoist type and a jig can advantageously be used to facilitate the mounting of the bottles 103 inside the storage cassette 102.

Afin de bloquer la cassette de stockage 102, on agence un dispositif de blocage 7 entre la première tôle 1 et la deuxième tôle 2. Plus particulièrement, une pluralité d'ensembles vis/écrou est installée dans la cassette de stockage 102 comme on peut notamment le voir en figure 10 et permet de relier la première tôle 1 à la deuxième tôle 2.In order to block the storage cassette 102, a blocking device 7 is arranged between the first sheet 1 and the second sheet 2. More particularly, a plurality of screw/nut assemblies are installed in the storage cassette 102 as can be see it in figure 10 and connects the first sheet 1 to the second sheet 2.

En figure 11, on insère la cassette de stockage 102 dans une structure primaire 101 afin de former le cadre de stockage 100. Un système de levage de type palan ou grue peut être utilisé.In figure 11 , the storage cassette 102 is inserted into a primary structure 101 in order to form the storage frame 100. A lifting system of the hoist or crane type can be used.

En figure 12, on règle et solidarise la cassette de stockage 102 à l'intérieur de la structure primaire 101 du cadre de stockage 100 par l'intermédiaire de liaisons mécaniques mobiles 8, perpendiculaires à la direction de la première tôle, au niveau de la première tôle 1 et de liaisons mécaniques fixes 9 au niveau de la deuxième tôle 2.In figure 12 , the storage cassette 102 is adjusted and secured inside the primary structure 101 of the storage frame 100 by means of movable mechanical links 8, perpendicular to the direction of the first sheet, at the level of the first sheet 1 and fixed mechanical connections 9 at the level of the second sheet 2.

Les liaisons mécaniques comprennent par exemple des systèmes à vis et écrou ou vis et taraudage ou goujon et écrou et/ou boulon ou tout autre système approprié permettant de solidariser la cassette de stockage 102 dans la structure primaire 101 du cadre.The mechanical connections include, for example, screw and nut or screw and tapping or stud and nut and/or bolt systems or any other appropriate system making it possible to secure the storage cassette 102 in the primary structure 101 of the frame.

De préférence, les liaisons mécaniques fixes 9 bloquent la deuxième tôle 2 sur la structure primaire selon les trois directions dans l'espace (point fixe sans degré de liberté). Par exemple plusieurs vis 9 traversent des passages ménagés dans la deuxième tôle et fixent cette tôle 2 sur la structure primaire 101. A noter que cette deuxième tôle 2 peut comporter des orifices (en étoile ou autre) complémentaires de la forme extérieure de la seconde extrémité des bouteilles 103b pour en bloquer la rotation.Preferably, the fixed mechanical connections 9 block the second sheet 2 on the primary structure in the three directions in space (fixed point without degree of freedom). For example, several screws 9 pass through passages made in the second sheet and fix this sheet 2 on the primary structure 101. Note that this second sheet 2 may include orifices (star or other) complementary to the external shape of the second end 103b bottles to block the rotation.

Les liaisons mécaniques mobiles 8 bloquent la première tôle 1 sur la structure primaire 101 selon deux directions (blocage dans le plan de la première tôle 1) tout en autorisant un débattement limité de la première tôle 1 dans une direction perpendiculaire au plan de la première tôle 1. C'est-à-dire que la première tôle 1 peut se déplacer selon une direction parallèle à l'axe longitudinal des bouteilles 103, pour absorber notamment leur dilatation longitudinale (déplacement limité verticalement lorsque les bouteilles 103 sont disposées orientées verticalement selon les figures 9 et 10 par exemple). Ce mouvement limité a par exemple une amplitude de 5 à 30mm et notamment 20mm.The mobile mechanical connections 8 block the first sheet 1 on the primary structure 101 in two directions (blocking in the plane of the first sheet 1) while allowing a limited movement of the first sheet 1 in one direction. perpendicular to the plane of the first sheet 1. That is to say that the first sheet 1 can move in a direction parallel to the longitudinal axis of the bottles 103, in particular to absorb their longitudinal expansion (movement limited vertically when the bottles 103 are arranged vertically oriented according to the figures 9 and 10 for example). This limited movement has for example an amplitude of 5 to 30mm and in particular 20mm.

Ceci permet également d'absorber également les variations de dimensions entre la cassette de stockage 102 et la structure primaire 101 du cadre (pour s'adapter aux tolérances dimensionnelles longitudinales et/ou de dilatation).This also makes it possible to also absorb the variations in dimensions between the storage cassette 102 and the primary structure 101 of the frame (to adapt to the longitudinal dimensional tolerances and/or expansion).

En figure 13, on réalise le lyrage et on installe les systèmes de distribution de gaz 10, puis on ferme la structure primaire 101.In figure 13 , the lyring is carried out and the gas distribution systems 10 are installed, then the primary structure 101 is closed.

Enfin, comme illustré en figure 14, on met en place des équipements 11 (tôles, renforts, façade utilisateurs...) en faces latérales du cadre de stockage 100 formé. Dans le cas d'un cadre de stockage 100 de bouteilles 103 horizontales, on retourne au sol le cadre de stockage 100 sur sa partie inférieure pour le mettre à l'endroit.Finally, as shown in figure 14 , equipment 11 (plates, reinforcements, user facade, etc.) is placed on the side faces of the storage frame 100 formed. In the case of a storage frame 100 of horizontal bottles 103, the storage frame 100 is returned to the ground on its lower part to put it upright.

Le montage d'une cassette de stockage 102 selon l'invention dans un cadre de stockage 100 selon un deuxième mode de réalisation va maintenant être décrit en référence aux figures 19 à 23.The mounting of a storage cassette 102 according to the invention in a storage frame 100 according to a second embodiment will now be described with reference to the figures 19 to 23 .

Le deuxième mode de réalisation du cadre de stockage 100 selon l'invention diffère du premier mode de réalisation en ce que la deuxième tôle 2 de la cassette de stockage 102 est supprimée et remplacée par une portion de la structure primaire 101.The second embodiment of the storage frame 100 according to the invention differs from the first embodiment in that the second sheet 2 of the storage cassette 102 is removed and replaced by a portion of the primary structure 101.

Plus particulièrement et comme illustré en figure 19, la structure primaire 101 présente une pluralité de logements 101b ménagés dans une portion de ladite structure primaire 101. Dans une première étape de montage, on positionne des éléments intermédiaires 101c ou entretoises dans lesdits logements 101b de manière à assurer l'interface entre les bouteilles 103 et la structure primaire 101.More particularly and as illustrated in figure 19 , the primary structure 101 has a plurality of housings 101b formed in a portion of said primary structure 101. In a first assembly step, intermediate elements 101c or spacers are positioned in said housings 101b so as to provide the interface between the bottles 103 and the primary structure 101.

Comme on peut le voir à la figure 20, chaque au moins un élément intermédiaire 101c est conformé pour recevoir et épouser la forme de chaque logement 101b ménagé sur la structure primaire 101 sur une face extérieure.As can be seen at the figure 20 , each at least one intermediate element 101c is shaped to receive and match the shape of each housing 101b provided on the primary structure 101 on an outer face.

Puis, on place les bouteilles 103 dans chaque élément intermédiaire 101c comme visible en figure 21. Chaque élément intermédiaire 101c est conformé pour recevoir et épouser la forme de la seconde extrémité 103b de chaque bouteille 103 sur une face intérieure.Then, the bottles 103 are placed in each intermediate element 101c as seen in figure 21 . Each intermediate element 101c is shaped to receive and match the shape of the second end 103b of each bottle 103 on an inside face.

Ensuite, on positionne la première tôle 1 au niveau de la première extrémité 103a de chaque bouteille 103.Then, the first sheet 1 is positioned at the first end 103a of each bottle 103.

Enfin, comme illustré en figure 23, on réalise le lyrage c'est-à-dire le montage du système de lyrage et robinetterie 10 équipant le cadre de stockage 100, par cohabitation avec les sorties de robinets montés à la sortie des bouteilles 103, et on installe les systèmes de distribution de gaz, puis on ferme la structure primaire 101 et on met en place des équipements 11 (tôles, renforts, façade utilisateurs...) en faces latérales du cadre de stockage 100 formé. Dans le cas d'un cadre de stockage 100 de bouteilles 103 horizontales, on retourne au sol le cadre de stockage 100 sur sa partie inférieure pour le mettre à l'endroit.Finally, as shown in figure 23 , the lyrage is carried out, that is to say the assembly of the lyrage system and fittings 10 fitted to the storage frame 100, by cohabitation with the outlets of taps mounted at the outlet of the bottles 103, and the distribution systems are installed of gas, then the primary structure 101 is closed and equipment 11 is put in place (plates, reinforcements, user facade, etc.) on the side faces of the storage frame 100 formed. In the case of a storage frame 100 of horizontal bottles 103, the storage frame 100 is returned to the ground on its lower part to put it upright.

Dans une variante de réalisation représentée en figure 24, le cadre de stockage 100 comprend un dispositif de verrouillage comprenant au moins un organe de verrouillage 12 configuré pour traverser la structure primaire 101 et également la seconde extrémité 103b de la bouteille 103 lorsque cette dernière est creuse.In a variant embodiment shown in figure 24 , the storage frame 100 comprises a locking device comprising at least one locking member 12 configured to pass through the primary structure 101 and also the second end 103b of the bottle 103 when the latter is hollow.

Lorsque le cadre de stockage 100 a une capacité de plusieurs cassettes de stockage 102, on réalise le montage de chaque cassette de stockage 102 indépendamment comme illustré aux figures 15 et 16. Puis on regroupe les cassettes de stockage 102 et on les assemble dans la structure primaire 101 qui les accueille comme illustré aux figures 17 et 18.When the storage frame 100 has a capacity of several storage cassettes 102, each storage cassette 102 is mounted independently as illustrated in figures 15 and 16 . Then the storage cassettes 102 are grouped together and they are assembled in the primary structure 101 which accommodates them as illustrated in figures 17 and 18 .

Pour un cadre de stockage 100 de bouteilles verticales, le cadre de stockage 100 est positionné au sol sur sa face inférieure. Pour un cadre de stockage 100 de bouteilles horizontales, le cadre de stockage 100 est positionné au sol sur un de ses faces latérales.For a storage frame 100 of vertical bottles, the storage frame 100 is positioned on the ground on its underside. For a storage frame 100 of horizontal bottles, the storage frame 100 is positioned on the ground on one of its side faces.

Dans l'exemple illustré aux figures 15 à 18, une cassette de stockage 102 contient de quatre à seize bouteilles 103. Un cadre de stockage 100 conçu selon l'invention est construit de manière modulaire avec une à quatre cassettes de stockage 102. Par exemple un cadre de stockage 100 de seize bouteilles 103 de l'invention peut être conçu à partir d'une cassette de stockage 102 de seize bouteilles. Un cadre de stockage 102 de soixante-quatre bouteilles 103 est conçu à partir de quatre cassettes de stockage 102 de seize bouteilles 103.In the example shown in figures 15 to 18 , a storage cassette 102 contains four to sixteen bottles 103. A storage frame 100 designed according to the invention is constructed in a modular manner with one to four storage cassettes 102. For example a storage frame 100 of sixteen bottles 103 of the invention can be designed from a storage cassette 102 of sixteen bottles. A storage frame 102 of sixty-four bottles 103 is designed from four storage cassettes 102 of sixteen bottles 103.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés aux figures annexées. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiments described and shown in the appended figures. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
